Benefits of technology

[0006]Accordingly, the primary object of the present invention is to provide a flexible thin-type light-emitting-diode circuit substrate which includes a reflector having a highly heat dissipative function and flexibility, as well as being able to be formed integrally.

Problems solved by technology

However, the ordinary printed circuit board is not provided with a good heat transfer effect, and therefore is not able to quickly remove heat energy produced by the light emitting diodes when illuminating, thereby affecting a luminous efficacy and a lifetime of usage of the light emitting diodes.
Moreover, for an existing light-emitting-diode lamp strip or array which is formed by arranging the plural light emitting diodes on the printed circuit board, a reflector should be assembled additionally that a light condensing effect can be produced to improve brightness of forward illumination, thereby allowing a manufacturing process to be tedious and time consuming.

Embodiment Construction

[0020]Prior to describing details of the present invention, it is noted that a same number is used to represent similar elements hereinafter.

[0021]Referring to FIG. 1 and FIG. 2, it shows a preferred embodiment of a flexible thin-type light-emitting-diode circuit substrate, in accordance with the present invention. The preferred embodiment of the present invention is a long-strip circuit substrate 1 comprising a bottom copper layer 11, a top copper layer 12, and an insulation layer 13 which is interlined between the bottom copper layer 11 and the top copper layer 12. The insulation layer 13 can be formed by heat conducting insulation adhesive to glue together the bottom copper layer 11 with the top copper layer 12 and to allow the bottom copper layer 11 not to be electrically connected with the top copper layer 12. The top copper layer 12 is defined with a wiring zone 21 and two reflection zones 22 which are located respectively at two opposite sides of the wiring zone 21 and are ad...

Abstract

A flexible thin-type light-emitting-diode circuit substrate includes a bottom copper layer, a top copper layer, and an insulation layer which is interlined between the bottom copper layer and the top copper layer such that the bottom copper layer cannot be electrically connected with the top copper layer. The top copper layer is defined with a wiring zone, and the wiring zone is formed with a circuit pattern for electrically connecting at least one light emitting diode.

Description

BACKGROUND OF THE INVENTION[0001]a) Field of the Invention[0002]The present invention relates to a light-emitting-diode circuit substrate, and more particularly to a flexible thin-type light-emitting-diode circuit substrate and a light-emitting-diode lamp strip which is formed by applying that circuit substrate.[0003]b) Description of the Prior Art[0004]As being provided with advantages of energy saving, environmental friendliness, high brightness and a long lifetime of usage, a light emitting diode has gradually replaced a conventional light source to be broadly applied in illuminating, an annunciation lamp, a bulletin board of advertisement and a liquid crystal display.[0005]The light emitting diode is a point light source; therefore, in order to increase a range of illumination, for an ordinary illuminating device or electronic device using the light emitting diodes as the light source, a plurality of the light emitting diodes are arranged and configured on a printed circuit boar...
